True or false, if false what would the correct term be?

False

To correct this, change "difference" to "sum"

In math, the term "difference" means we subtract two numbers or variable expressions. For example, 10x-5 is a difference. The term "sum" means we add two expressions, so something like x^2+5x is a sum.

The formula for finding the length of the hypotenuse (c) when given the legs a and b is this

We are taking the square root of the sum

This is based off the pythagorean theorem

$8

step-by-step explanation:

it is pretty much backwards.

you take the 4x2 multiply that, and that is = $8

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
